Swine influenza (also called H1N1 flu, swine flu, hog flu, and pig flu) is an infection by any one of several types of swine influenza virus. Swine influenza virus (SIV) is any strain of the influenza family of viruses that is endemic in pigs. As of 2009, the known SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H3N1, H3N2, and H2N3.

Swine influenza virus is common throughout pig populations worldwide. Transmission of the virus from pigs to humans is not common and does not always lead to human influenza, often resulting only in the production of antibodies in the blood. People with regular exposure to pigs are at increased risk of swine flu infection. The meat of an infected animal poses no risk of infection when properly cooked.

The Swine flu has been compared to other similar types of influenza virus in terms of mortality: "in the US it appears that for every 1000 people who get infected, about 40 people need admission to hospital and about one person dies". There are fears that swine flu will become a major global pandemic in the winter months, with many countries planning major vaccination campaigns.

Influenza is quite common in pigs; the main route of transmission is through direct contact between infected and uninfected animals.

People who work with poultry and swine, especially people with intense exposures, are at increased risk of zoonotic infection with influenza virus endemic in these animals, and constitute a population of human hosts in which zoonosis and reassortment can co-occur. Other professions at particular risk of infection are veterinarians and meat processing workers, although the risk of infection for both of these groups is lower than that of farm workers.

Main Signs and symptoms of swine flu:

According to the Centers for Disease Control and Prevention (CDC), in humans the symptoms of the 2009 "swine flu" H1N1 virus are similar to those of influenza and of influenza-like illness in general.

Symptoms include fever, cough, sore throat, body aches, headache, chills and fatigue. The 2009 outbreak has shown an increased percentage of patients reporting diarrhea and vomiting. The 2009 H1N1 virus is not zoonotic swine flu, as it is not transmitted from pigs to humans, but from person to person.

The most common cause of death is respiratory failure, other causes of death are pneumonia (leading to sepsis), high fever (leading to neurological problems), dehydration (from excessive vomiting and diarrhea) and electrolyte imbalance. Fatalities are more likely in young children and the elderly.

Prevention :

According to Ayurveda, prevention is always better than cure, and the primary aim goal of Ayurveda is to maintain the health of a healthy person. As stated: "Swasthasya Swasthya Rakshanam…" here are the few preventive measures according to modern science and Ayurveda.

Prevention of swine influenza has three components:

•prevention in swine,

•prevention of transmission to humans,

•and prevention of its spread among humans.

The current trivalent influenza vaccine is unlikely to provide protection against the new 2009 H1N1 strain, so the control of swine influenza by vaccination has become more difficult in recent decades. But you don't worry even if you are not vaccinated. Start practicing Pranayama, especially "hot Pranayama like Bhastrika and Kapalbhanti"! This will improve your lungs capacity and immunity to combat any infections from the viruses.

Swine flu cannot be spread by pork products, since the virus is not transmitted through food but it spreads between humans through coughing or sneezing and people touching something with the virus on it and then touching their own nose or mouth.

The swine flu in humans is most contagious during the first five days of the illness although some people, most commonly children, can remain contagious for up to ten days. Diagnosis can be made by sending a specimen, collected during the first five days for analysis. So as soon as you feel discomfort with symptoms like sneezing, coughing and any other respiratory symptoms, start to have herbal tea, which is very common practice in India. The recipe of such herbal tea knows almost every mother or grandmother knows in India! well, if you don't know: let me explain:

Boil approximately 200ml of potable water, till it remains half and mix the following herbs in it.

•Juice of 10 to 15 fresh leaves of Tulasi (Basil),

•5 ml of fresh ginger root juice,

•half spoon powder ofcloves,

•half spoon powder of cinnamon bark,

•half spoon powder of peppermint leaves,

•half spoon powder of cardamom,

•half spoon of turmeric powder,

•half spoon of rock salt

Mix all these properly, add one spoon of honey when the tea is luke warm and have it twice or thrice a day.

These all-around wonder spices are said to help detoxify the liver, fight allergies, stimulate digestion, and boost immunity. All these drugs have anti viral, cleansing and antioxidant properties. It helps the free flow of oxygen to the brain, helps enhance digestion and circulation and stimulates the appetite. They are excellent for balancing Vaata and Kapha, which are the prominent Dosha in Swine influenza or any other respiratory track infections.

•Recommendations to prevent spread of the virus among humans include using standard infection control against influenza. This includes frequent washing of hands with soap and water or with alcohol-based hand sanitizers, especially after being out in public.

•Chance of transmission is also reduced by disinfecting household surfaces, which can be done effectively with a diluted chlorine bleach solution.

•Experts agree that hand-washing can help prevent viral infections, including ordinary influenza and the swine flu virus.

•Influenza can spread in coughs or sneezes, but an increasing body of evidence shows small droplets containing the virus can linger on tabletops, telephones and other surfaces and be transferred via the fingers to the mouth, nose or eyes.

•Alcohol-based gel or foam hand sanitizers work well to destroy viruses and bacteria.

•The Puja being done in Hindus has the similar disinfecting properties.Studies have shown that lighning the lamp of cow's Ghee has anti viral property. The Dhupana being done with the help of natural sticks (Agarbattis) and Guggulu has very effective disinfectant properties.

•Anyone with flu-like symptoms such as a sudden fever, cough or muscle aches should stay away from work or public transportation and should contact a doctor for advice.

•Social distancing is another tactic. It means staying away from other people who might be infected and can include avoiding large gatherings, spreading out a little at work, or perhaps staying home and lying low if an infection is spreading in a community.

•Public health and other responsible authorities have action plans which may request or require social distancing actions depending on the severity of the outbreak.

According to Ayurveda daily and dietary habits plays a major role in any disease. If your digestive fire is normal, your immunity will remain powerful and thus no infection can overrule you. So one should follow the ideal dietary regimen during seasons like monsoon and winter when the maximum chances are there for viral infections.

•One should avoid sleeping during the day hours.

•One should avoid traveling or being outdoors during the early hours of the day when there is dew and cold winds blow.

•Oil massage with oil possessing warm quality is beneficial.

•Clean and dry clothes should be worn.

•Individuals should avoid direct and strong cold winds.

•Avoid skipping meals.

•Try to move around the place of work instead of sitting in one place or do some kind of physical work. This will help you to refresh yourself, especially when you feel dull & lethargic.

•Try to avoid over exertion.

•Not delay or skip your meals, you should take meals at regular timings & in fixed quantities.

•Avoid damp, humid and cold weather, and environment.

•Avoid use of air conditioners.

•Drink a glass of water with two teaspoons of honey every day early in the morning.

•Always have fresh meals, prepared using minimum quantity of oil, or prepared with the help of Cow's ghee.

Ayurveda Treatment for Viral infections in cold seasons like Monsoon and winter:

If a person becomes sick with swine flu, antiviral drugs can make the illness milder and make the patient feel better faster. They may also prevent serious flu complications. For treatment, antiviral drugs work best if started soon after getting sick (within 2 days of symptoms).

Beside antivirals, supportive care at home or in hospital, focuses on controlling fevers, relieving pain and maintaining fluid balance, as well as identifying and treating any secondary infections or other medical problems.

The virus isolates in the 2009 outbreak have been found resistant to amantadine and rimantadine. In the U.S., on April 27, 2009, the Food and Drug Administration (FDA) issued Emergency Use Authorizations to make available Relenza and Tamiflu antiviral drugs to treat the swine influenza virus in cases for which they are currently unapproved.

In such condition following Ayurveda drugs may be started as soon as possible. Few of these drugs have been found very effective in current research works and are being practiced in India since thousands of years for combating various seasonal and viral infections.

•Sanjivani vati

•Sitopaladi churna

•Sanshamani vati

•Vasadi vati

•Trikatu

•Chyavanprash

•Yastimadhu ghan vati

•Haridrakhand

Panchakarma procedures like Nasya Karma and Sadya Vamana Karma are also very useful for all respiratory track infections.

It is advisable to remain under medical supervision of a qualified and experienced Vaidya. We have seen miraculous results of above said drugs in various viral infections in thousands of patients in our clinical experience.

There is no doubt that above said drugs and Panchakarma helps to expel Kapha from the body and also helps to stop or to slower the viral load from the body, which is ultimately responsible for high grade fever and other symptoms which are responsible for high rate of mortality
